happening to me right now,so im patiently waiting for my thing to get off the ground ,then i can respectfully resighn my position.
My sujestion ,don't put up with it .Find another position ,put in your 2 weeks and respectfully resighn (dont ever burn your bridges).

Talk to them NOW,chances are if they are closing they will try to worm thier way out of paying for it ,if you can, get your last check to include your vaca time .otherwise you may not find anyone when you get back to get your last check.
Ive been through 2 closures, your lucky you got notice.First place that closed that I was at the chef de cuisine told me days before they closed and if it wasnt for me nobody eles would have known till they showed up to find chains on the door.the second place gave us 2 weeks notice ,this was again because a rep told me he couldnt deliver because somebody had started going through the procces of setting up an acount for that address ,and he knew when we were closing( again I informed my staff after I told the GM he would have to fire me 'cause I was telling the staff anyway).
At any rate owners get shady as hell when they are forced to close ,so check now and get as much out now as you can( I generally dont condone this but don't be afraid to grab some extra stuff to get what you can out of the closure) as the owners will more than likly end up screwing you over.
start talking to your reps (swiss chalet ,Albert uster) I dont know who you use ,but your reps will have a good idea of who needs what around town ,and if they like you will often talk you up to a perspective restaurant -this is one of those give a little take a little deals,this is when politics play if your good at it.
